I love this tool and use it all the time when I evangelize IPv6 to people.

Unfortunately, in any lookup on the DNS page of the app fails with:

Error
network error

This is regardless of DNS type and regardless of being on AT&T's 5G network, Sprint's network, or any of the WiFi networks I have tested on. I am using mostly Samsung devices running Android 12. Other functions like Ping and Traceroute work just fine.

I think this is the same issue that was reported here: https://forums.he.net/index.php?topic=4116.0.

My uneducated guess is that there is a permissions problem in newer versions of Android with the particular function being used for the DNS part, because it definitely worked for me on earlier versions of Android and I don't think the app itself has changed in a while. Maybe it just needs a recompile with newer options? I don't know much about Android development, but I see notices all the time in apps saying something to that effect.

I use the app to show people that they are already using IPv6 without knowing it. We look at the Interface page and they see the IPv6 addresses on the cellular interfaces. Then we have fun doing DNS lookups of facebook.com and see the hidden words encoded in the IPv6 addresses.

It is a great tool and great for socializing IPv6 since everyone has a device it works on and can see how prevalent it is.
